Exploring Oat Husks as Aggregates in Limestone-Based Composites: Effects of Surface Treatments and Binder Selection on Mechanical Performance.

The viability of incorporating agricultural by-products, such as oat husks, not yet explored in limestone-based composites, as more sustainable alternatives for use as novel aggregates may be improved through the adoption of well-known valorisation strategies applied to other plant-based resources. In this context, this work innovates by assessing how treatments on oat husk surfaces and the choice of limestone-based binders impact the mechanical performance of composites. The strategy adopted to achieve these objectives, in addition to carrying out the physical and geometric characterisation of the husks, consists of treating the husks' surface using washing cycles in water, cement/pozzolan binder, and linseed oil.

How Concurrent Services Obscured Detection of Intervention Benefits: Part 2: Secondary Analysis of the PREP Trial for Frail Older Adults and Family Caregivers.

Family caregivers frequently use health and social services to support their caregiving. In evaluating care-giving interventions, however, researchers rarely examine the influences of such concurrent services on intervention effectiveness. In this Part 2 secondary analysis of data from the Oregon Health & Science University/Kaiser Permanente Northwest Region Family Care Study, we examined the moderating influences of concurrent services on intervention effectiveness.

How Tailoring Led to Variation in Care Issues, Dosage, and Outcomes: Part 1: Secondary Analysis of the PREP Trial for Frail Older Adults and Family Caregivers.

In family caregiving interventions for adults with health problems, tailoring has become the norm. Studies that evaluate tailored interventions, however, have rarely included intentional variation in dosage or explored the dosage-outcome association. In this Part 1 secondary analysis, we examine dosage and outcomes in intervention families ( = 116) who participated in the Oregon Health & Science University/Kaiser Permanente Northwest Region Family Care Study.

Injury Reduction Programs for Reducing the Incidence of Sport-Related Head and Neck Injuries Including Concussion: A Systematic Review.

Background: Sport-related head and neck injuries, including concussion, are a growing global public health concern with a need to explore injury risk reduction strategies such as neck exercises.

Objectives: To systematically review the literature to investigate: (1) the relationship between neck strength and sport-related head and neck injuries (including sport-related concussion (SRC); and (2) whether neck exercise programs can reduce the incidence of (a) sport-related head and neck injuries; and (b) SRC.

Methods: Five databases (Ovid MEDLINE, CINAHL, EMBASE, SPORTDiscus, and Web of Science) and research lists of included studies were searched using a combination of medical subject headings and keywords to locate original studies which reported the association between incidence of head and/or neck injury and neck strength data, or included a neck exercise intervention either in isolation or as part of a more comprehensive exercise program.

Is there any place for the variable angle proximal femoral plate? A case matched cohort study against the Dynamic Hip Screw system.

Introduction: The Variable angle Martin Plate (MP) is designed to offer patient-specific adaption for the treatment of intertrochanteric hip fractures. Its proposed benefits include optimization of lag screw placement, plate shaft congruence and reduced risk of failure. Often its use has been criticized as representing a poor reduction of the fracture.
